Hey guys, so I hooked up a LC-1 wideband to my vh41de to check the A/F ratios. Once it has warmed up it idles quite lean, +17 so I've been reluctant to run it too long. It starts to blow a whitish sort of smoke but it comes and goes only doing it once warmed up. Im positive its not coolant being burnt, Could the VTC cause this? Its got me baffled cause its a stock ecu and tune and normally they run quite rich from factory.
